PLC Relay is the perfect interface between control and system peripherals

PLC RELAY from Phoenix Contact is the most complete and innovative coupling relay family in the market. Whether in 6.2 mm or in 14 mm wide housings, PLC RELAY offers the right solution for almost all industrial applications.

EMR or SSR as alternatives

The basic terminal block of the PLC module can be equipped with either a pluggable electromechanical or a wear-free solid state relay. This guarantees extremely service-friendly operation. In the 6.2 mm wide housing, the REL-MR...21 can be used with power contact and a maximum switching capacity of 250 VAC / 6 A. Multi-layer contact relays are naturally available in a 1-PDT as well as in a 2-PDT version.

Modules with spring-cage and screw connection are of the same shape

Almost all modules are available in the proven screw connection method, and also in the spring-cage connection method. As the housings - whether 6.2 mm or 14 mm wide, screw or spring-cage connection - are of the same shape, the same accessories can be used in all modules and accordingly the same potentials can be bridged between them. PLC-RSP...21-21 consists of the 14 mm wide basic terminal block and a power relay with two PDT contacts.

Easy connection to the system cabling

The PLC Relay together with the VARIOFACE system cabling forms an unbeatable team. Simply connect eight PLC interfaces in series and plug the PLC-V8 adapter into the bridge shafts of the modules. The complete and polarized wiring between PLC control and interface level is achieved in a few minutes. The channel-specific mixing of electromechanical relay and solid state relay is possible.

Interference voltages are safely absorbed

Coupled interference voltages are no rarity in the industrial environment. This interference voltage, often encouraged by very long control cables, can lead to the relays not dropping out in spite of "zero signals". The PLC...SO46 version is especially designed for such cases. An integrated circuit ensures that coupled interference voltages are absorbed and the relay module functions without problem.
